Specification of Letters Patent. Patented 113,1, 28, 1922.

Application filed December 19, 1919. Serial No. 346,033.

To all whom it may concern:

Be it known that I, RALPH R. CRooxER, a citizen of the United States, residing in the city of Council Bluffs, in the county of Pottawattamie and State of Iowa, have invented certain new and useful Improvements in Packing Connections, and have described the same in the following specification, illustrated by the accompanying drawings.

My invention relates to a non-leakable connection between telescoping pipes, or other pipes, or between a pipe or a pump casing and a container of a gaseous or liquid fluid, and to packing devices which are adapted to be used in connection with piston-rods, regulator rods, pump plungers, slide valve stems, and the like, and individually comprise a tubular] casing and a follower adjustable therein. It is the main object of the invention to adapt a packing device to connect with the inside of a barrel or like receptacle imperviously and without leakage; to render a single packing connection applicable alternatively to different cyl, inders, pump tubes and casings, steam dome casings and other containers, as convenience may equire; to adapt a packing connection, when applied to a barrel or other container, as a pump head or as a holder of a pump casing, to hold the pump or casing immovably in its given or desired position in the container; and in general to increase the adaptability and efliciency of packing connections. To accomplish this object, I incorporate in my improved packing connection as part thereof, a stuffing box which has a gland in one end and is formed with external screw threads on the other end and with internal screw threads at each end.

In said drawings, illustrating the best manner in which I have contemplated applying the principles of the invention, l is a side elevation of a packing connection which is constructed in accordance with these principles. Fig. 2 is an axial section of the same, with two pipes joined thereby. Fig. 3 is an axial section of a modified form of the device, applied to a tank or similar container. 7

In these drawings the stuffing box proper is a hollow casting, of general cylindrical form, which is denoted in Figures 1 and 2 by the numeral 1, and in Fig. 3 by 1. Ex-

ternally it is formed with a projecting angular formation 2 for engagement with a wrench, and with the screw threads 3 on that end of the box which for convenience may be termed its inner or lower end. Internally it has the axial bore 4 and the central coaxial chamber 5 which is larger than the bore. It has also in its opposite end portions the cylindrical chambers 6 and 7 which are coaxial with the bore and internally screw-threaded. The gland or follower 8 is tubular and externally screw-threaded. It has an angular top flange 9 for engagement with a wrench, and a central bore continuous with the bore 4 as well as of the same diameter, and is adapted to act upon the fibrous stuffing 10 in the chamber 6. In the modification shown in Fig. 3, the box, 1, is provided with an outlet port 14 and a radially directed nipple 11, which leads from the chamber 5 and is adapted to connect with a delivery pipe. In the use of this modification as a pump-head, space around the pump rod must be allowed in the bore 4 between the chambers 5 and 7 for the passage of the pumped fluid up into the chamber 5 from the pump casing below. 1

Such being the construction of the device, its applicability and operation are now to be explained. It may be applied to a dome casing, a barrel, a. tank or other container of a liquid or gaseous fluid, and imperviously united with the container, by screwing it into a bunghole, or screw-threaded aperture of the container 12, as shown in Fig. 3, and may be transferred successively from one such position or container to another, as may be desired. It may be applied to a pump casing 13 in any desired position of longitudinal adjustment thereon, as shown in Fig, 2, and may be held immovably in that position by screwing down the gland 8 upon the stufling 10.

I claim as my invention '1. In a packing connection a stufling-box having an axial bore, anexternal screw thread, a central chamber larger than the larger than the bore and coaxial in each end of the box.

2. A packing connection comprising a stufiing-box' having an external screw thread, an axial bore, a middle chamber therewith,

larger than the bore, an outlet from the middle chamber, and an internally threaded chamber in each end of the box.

3. A packing connection comprising a stufling-box having an axial bore, a central ch amber larger than the bore, an outlet from the chamber through the side of the box, an external screw thread on one end of the RALPH R. CROCKER.
